QT 4.7: GdkPixbuf-WARNING **: Bug! loader 'png' didn't set an error on failure

I had similar errors during execution of an application inside QtCreator - custom icon theme for gnome caused problem - after switching it to default / standard ones everything's fine.

Hi,
sorry to writing to topic one month old, but i had this problem too and found a solution, so I think it will be handy for someone:

Just run as root:

update-mime /usr/share/mime/
update-mime-database /usr/share/mime/
gtk-update-icon-cache /usr/share/icons/YourTheme

Logout/Login and it will be all right now :-)

sudo gtk-update-icon-cache /home/kelvin/.icons/Faenza

sudo update-mime /usr/share/mime/
sudo update-mime-database /usr/share/mime/

Hi I'm new to this forum. I've just tried the above and I'm getting the following error under Linux Mint. Any idea what I'm doing wrong?
